Mikhail Antonov updated HBASE-11092:
------------------------------------
Description:
As discussed in comments to HBASE-10915, we need to have a proper way to
retrieve instance of consensus provider, and Server interface seems the right
one.
Since Server interface lives in hbase-client maven module, the following
approach is implemented in this patch:
- hbase-client module has very basic (almost marker) interface
ConsensusProvider to return instance of consensus provider from the Server
- hbase-server module has BaseConsensusProvider which defines the consensus
interfaces
- Implementations shall subclass BaseConsensusProvider
- whoever wants to get ConsensusProvider from raw Server interface on
hbase-server side, has to typecast: (BaseConsensusProvider)
